APPARATUS FOR UNPOWDERING SUGAR BODIES rma um. 21, 1929 Per' Patented June 24, 1936 erre 'rar rarer APPARATUS FOB UNIPGVVDERING SUGAR BIJES Application file-:1 November 531,

The present invention relates to an im- )rovement in or development of the a mara! tus describedin our German Patent No. 402,122, in which boXes or molds containing 5 powder and the sugar bodies cast therein are turned over for the their contents. y Y

In the apparatus according to the said Gorman patent a closure AHap closes the l0 filled box which is turned without interrup-V tion through 3G00 and the flap 1s openedV said apparatus was an improvementl upony those previously employed i'or the purpose, al

not inconsiderable number of sugar bodies are still broken, particularly when dealing with specially fragile bodies, for example, with those havino' a liquid illing or the like. This is to be attributed mainly to thel actthat the heio'ht of fall of the bodies from the edge of the closure flap on to the jolting sieve must still be too great in order to permit the further uninterrupted movement of the box without damage to the bodies already resting upon the jolting sieve. I

This drawback is remedied in accordance with the present invention by an arrangement in which the hap, after it has opened, in the inverted position oi the box, is moved after the manner of a jolting slide, so that the sugar bodies being allowed to iall and are received upon a conveyor device which conveys tliem outroi the machine. The closure iiap itself consists of` a perforatedsheet -me al plate so that the powder is permitted, i'or the most part, to drop through `the lap. and collect .in the lower portion of the machine, from which point it is again brought to the fillingpoint of the boxes. The remaining portion of the powder, together with the sugarL bodies, are'received upon the conveyor device, which is likewise constructed afterthe manner of a sieve, so that the powder is purpose of discharging slide Atherefrom without over the narrow sides of the box with an Y longitudinal sides rectangular flanges adapt- 1929, sei-m1 No. 1 -assis, @me in eem-.any apra e, 1929.

there separated con'ipletely from the bodies, and passes to the said powder collection point in the lower'portion or" the machine.A

Whereas in the well-known turning ap-` paratus the filled boi; introduced at any particular time executed a full turn through' 3G99, the arrangement in accordance with the present invention is such that two lpowder boxes are accommodated in the turning device. At each operation the device is 6G turned only to. the extent of 1800, and theA box that is situated at the bottom is emptied while the previously emptied boX is removed from'the topei the device and a newly filled box is substituted. 65

The drawing illustrates by way of cX- ampleone form of embodiment of the invention.

Fig. l is a View of the turning apparatus viewed in the direction of travel of the box;

Fig. 2 is a vertical section through the apparatus along the line aff-b of Fig. l, viewed in the direction of the arrows. i The main shaft l orn the turning apparatus is supported in bearings in the side parts or fra-mes 2 of the machine. Each frame 2 has a bearing bush carrying cam discv 3 and extending through theframe to serve as the bearing for the said shaft, and-for the purposehereinafter described. On the main L shaft l, which turns intermittently .to the extent of o each time, there are secured rails 5, which support, during their rest position, the filled box i which is introduced at theA top ot' the apparatus.: The shaft l has also secured thereon two shields 6 which. carry rails 7 adapted to guide therbox atrv its narrow sides, and which rails 7 extend each attached by means or one double-joint lever 8. These closureA flaps 9 havel at `their ed to extend over the longitudinal walls of' the boxes. At that end `which is opposite to the point of attachment (at the leftin Fig. l), each closure flap 9 has on 'its'tlanges on each side a bolt l0, which bolts are en-y 19S gaged by a device hereinafter described for the opening and closing of the flaps.

The flap 9 which is situated at the top, at the stoppage otl the turning apparatus, assumes such a position that the filled box et can move into position under its bent-over side edges, until the box is supported upon the rails 5 which engage the bottom ot the box close to its foot-pieces e1. After its introduction the box is lifted in such a way that the iianges of the Hap 9 extend over its longitudinal side walls and the box is thus completely closed by the flap. rFhis lifting of the box is effected by the following mechanism.

Upon the main shaft 1 there is secured under each of the two narrow sides of the powder box 4 a guide part 11 carrying two slide rods 12 which support at their ends two cross-rails 13, so that the latter can be moved with the said rods 12 towards and from the bottoms of the boxes. At the center part thereofeach rail 13 has a projection which extends through the adjacent shield G and carries a roller 14 which runs upon the said cam disc 3 as long as the apparatus is turning. The hub of the said cam disc 3 extends through the frame 2, and at the outside oit the traine the hub carries a crank 15, connected to a pull-rod 1G which is moved from any desired point of the machine in such a way that a slight partial rotation is imparted to the cam disc 3 through the medium of the said crank. Thelifting contrivance operates as follows:-

The uppermost box a is first received by the rails 5, while the rollers 14 rest upon the lowest points of the cani discs 3, so that the foot-pieces tl of the boxes are Jfree to move over the rails 13 ot the lifting device. As soon as the box has come to rest in the turning apparatus the`cam discs 3 are turned by means of the pull rod 16, in the opposite direction to that of the arrow of Fig. 2, and to such an extent that the rollers 14 rest upon thehigh points of the said cani discs. The box et is thusv raised toward the flap 9 in such a way that the box is received between the lateral fianges ot the flap and is completely closed thereby. The shaft 1 is then turned in the direction of the arrow voit Fig. 2 to the extent'of 180, so that the lilled box is inverted and is brought to the ylower part of the apparatus. During this turning of the entire apparatus the said cam discs 3 are partially rotated so as to bring them to their initial position, so that the box 1, previously emptied and again turned upward, is again lowered upon the rails 5 when the partial rotation of the apparatus has been eiected, since the rollers 111 correspond- `ing to the box in question rest upon the lowest points in the cam discs 3.

The rails 13 are provided, with raised parts 18 which engage between the foot-pieces 4 of the boxes in order to prevent lateral displacement of the box when the latter is again released by the opening of the iiap 9 and is no longer held by the lateral flanges ot said flap.

The openine of the flap 9 in the inverted state of the box is eiiiected by the following contrivance.

0n the shield 6 located at the lett in Fig. 1 there are provided guides 17 for two pairs of slide rods 18 and 19. Each of these pairs oit rods is connected at one of its ends by means of a cross-bar 18 and 19 respectively, each of which cross-bars carries at its middle a roller 18 and 19 respectively. At the ends thereof opposite to the said cross-bars 18 and 19 respectively, the said pairs of rods 18 `and 19 carry on each ot their individual rods a slotted arm 2O and 20 respectively. r)The slotted arms 2O of the pair of rods 18 engage the said bolt 10 of the flap 9 located at the top in the apparatus while the slotted arms 20 ot the pair et rods 19 engage the bolt 10 of the lower iiap 9. vThe trame Q at the lett side 1 has secured thereto a member 21 having an endless cam 'groove in which the rollers 18 and 19 of the two pairs of rods 18 and 19 are guided. rPhe said groove is so shaped that during the turning operation the Hap 9 of the box which is moving downwardly remains closed until shortly before it reaches its coinpetely inverted position, to open rapidly onlyat that time, and so that during the succeedii'ig movement the flap 9 ot the powder box that is moving upwardly is closed again after the traversing.;` of about three-quarters of the distance.

Then a powder box 9 reaches the lowermost part ot' the apparatus, the powder and the sugar bodies that have been cast in the box are supported upon the {iap 9 and after the latter has been opened it forms an obliqnely arranged slide constructed ot perforated sheet metal, in order that the powder may for the most part pass through the flap which, in being opened, is swung downwardly about one of its narrow sides into such an oblique position that sliding movement of the sugar bodies is still prevented. In order to cause the bodies to glide or move gently from the flap, the latter, as soon as it has been opened, is subjected to a jolting movement. Close below the lowermost extremity of the oblique iiap is a conveyor grating 22 which receives the sugar bodies delivered from the flap. Through this conveyor grating' or sieve 22 by which the bodies are conveyed out ot the machine, a further elimination of the powder may be eiiqected at the same time. The powder falling through the flap 9 as well as that falling through. the conveyor a2 is conducted, by means not shown in the drawing, to a point within the machine from which it can be conveniently conveyed for further and iinfor turning the box to an inverted posimediate utilization for the renewed filling of the emptied powder' boxes.

For effecting the said jolting movement of the opened and oblique flap 9 the following mechanism is provided:

ln the right-hand frame 2 of the apparatus guides are provided for a pair of slide rods adapted to move in a longi tudinal direction. At the interior of the apparatus the said rods 23 are connected by means of a eouplingspart 2li and at the exterior of the apparatus the ends of said rods are connected by means of a cross piece A push-rod 26, actuated from any iflesired point of the apparatus, is connected to the cross-piece 25 and, during the stopinige' of the turning apparatus imparts reciprocating motion to the parts 23, '24, 9,5. The coupiing part 2li has on its upper side a groove which is engaged by the lever S of the flap 9 that has at any particular time been brought to the lowerinost position, so that this lever ,8 and consequent-ly the flap Sl are coupled with the parts 23--26 and partieipate in their movements. During this jolting motion the flap 9 with its two bolts i0 is guided inthe slots of the arms Sil) and i0 respectively.
